Cheers thanks guys, starting to run out of room and thought lying on a nice cool water tank would help keep me cool as well as being out of the way.... Oh well back to he drawing board. Should be ok with the class the engine is a gas turbine....

Thanks for the video link Mate, you have a good looking build going there & that was the first clue to your Oz location. You can be anywhere with an accent just like I am but the true blue square tubing gives it away. Is the upside down quick change relative to engine rotation? Sid.

In the build diary you will see I needed to chop up the turbine gearbox to get the power output in the right direction as well as the right rpm. The diff in that position means I can have an almost level drive shaft, but I needed a special reverse direction ring & pinion. The plumbing is mainly to keep the input shaft bearings cool since they are at the top now in air and not in the oil bath at the bottom.
